# Provides: lirc
# Required-Start: $remote_fs
# Required-Stop: $remote_fs
# Default-Start: 3 5
# Default-Stop: 0 1 2 6
# Short-Description: lirc daemon
# Description: The main task of lircd is to decode the infrared
# signals and provide an uniform interface for client applications

# Shell functions sourced from /etc/rc.status:
# rc_check check and set local and overall rc status
# rc_status check and set local and overall rc status
# rc_status -v ditto but be verbose in local rc status
# rc_status -v -r ditto and clear the local rc status
# rc_status -s display "skipped" and exit with status 3
# rc_status -u display "unused" and exit with status 3
# rc_failed set local and overall rc status to failed
# rc_failed <num> set local and overall rc status to <num>
# rc_reset clear local rc status (overall remains)
# rc_exit exit appropriate to overall rc status
# rc_active checks whether a service is activated by symlinks
# rc_splash arg sets the boot splash screen to arg (if active)

# Reset status of this service

# Return values acc. to LSB for all commands but status:
# 0 - success
# 1 - generic or unspecified error
# 2 - invalid or excess argument(s)
# 3 - unimplemented feature (e.g. "reload")
# 4 - user had insufficient privileges
# 5 - program is not installed
# 6 - program is not configured
# 7 - program is not running

# Note that starting an already running service, stopping
# or restarting a not-running service as well as the restart
# with force-reload (in case signaling is not supported) are
# considered a success.
